Clarks — Regarding request for return of shoes

I had purchased a pair of shoes online from Clarks website and
I have been trying to raise a return request for the order which I have received. My order id is FY61C3477B01209656F2

The shoes which I had received it on 27th October were 3 years old
and on the box the date of manufacture was written as august 2021
but when I opened the box, I found that the shoes were actually manufactured in September 2019. This is unacceptable.

The shoes are about to be 3 year old by next month and I never expected to receive such an old pair of shoes from Clarks.

Their customer care no. doesn't work all day and your response is absurdly slow and this is not expected from such a reputable company.

I wish to return my order and my order Id for the order is :
FY61C3477B01209656F2

I request you through medium of this website to kindly process my request for the return of these shoes as soon as possible.
